• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (thu sach)) ky nang xa hoi. thien ((van cam) OR (van cau)) truc va thanh hai hau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (thu sach)) ky nang xa hoi. thien ((van cam) OR (van cau)) truc va thanh hai hau tren".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (thu sach)) ky nang xa hoi. thien ((van cam) OR (van cau)) truc va thanh hai hau tren*.
